Many web apps and even websites like to prompt users to add their page to their iPad's home screen. This is particularly useful for web apps since if the website is launched from the home screen, it will appear in full screen mode (without safari bar).

Is there data somewhere on whether the add to your home screen prompt actually works? Or how many people actually add web pages to their home screen?

If you could elaborate on the problem you are trying to solve, that might make for an easier question to answer. As stated, an answer of "yes" or "no" could be offered. We have a nice guide on How to Ask to help guide you if you find that no answers arrive after a few days.
